libcanberra is used to play system sounds and any Gtk application tries to load it automatically at startup. Presumably it is not a hard requirement for Pale Moon.A quick web search on the error message will give you the instructions to install the module on your distro, if you want that.

As for the second error message, I’m not sure. You’re not running palemoon with sudo, are you? Or is it the installer?
